kernel-build.eclass: add special-case for sparc arch/ directory Unfortunately, we still have a mess wrt dual-bitness arches. For sparc, there's arch/sparc, with ARCH=sparc being "whatever the toolchain is", ARCH=sparc32 being "give me a 32-bit kernel", and ARCH=sparc64 being "give me a 64-bit kernel". You do, seemingly, need to actually pass ARCH=sparc64 to guarantee correct results, as various kernel Makefiles check for the ARCH value, even though ARCH=sparc will pop out a 64-bit kernel. (I originally updated toolchain-funcs.eclass's tc-ninja_magic_to_arch, but we later found that doesn't look particularly sturdy. Per at the very least 5ba800962a80d4158b73fb91a7779df7b770c750 ("kbuild: update ARCH alias info for sparc") upstream, although it seems to go back a fair bit earlier, ARCH=sparc when building the kernel means "sparc64" if on a sparc64 host.)
